February Contractor Update, some new data - Happy New Year!

Dear Contractors,


You may find these numbers from 12,559 HPwES jobs shocking.  They may make you uncomfortable.  Certainly this is a very different look than the day to day look at individual jobs.  When you look at larger numbers patterns emerge.  But don't you want to KNOW how you are doing?!?

TRACKING MATTERS - Bill Gates says just the act of measuring causes polio cases to drop in African Nations.  The premise is operators use tools more effectively when they know their success, and their failure, will be open to public scrutiny.  Carrot and stick.  I believe the same is true for energy which is why I've been digging for these numbers.  Taking a common phrase one step further; Measuring Causes Management.

AMBIVALENT. INCOMPETENT. FRAUDULENT. Is that how you want your company, or this industry to look?  Sure, there's no upside to diligence that nobody measures but that is at an end.  As you can see, measurement is happening.  There will be great reward for accuracy in the form of public confidence and capital access.  This is the path to monetizing Energy Efficiency as a resource.  I've got a carrot and a stick here, let's not have to use the stick.  

REVIEW:
Some of you may be aware that last spring I requested and received a large amount of data under the Freedom of Information Act from NYSERDA regarding your HPwES projects.  I now have blower door numbers for all of your projects for the past two years through November.  Test in, projected, and test out.  Below is a representation of how well you have done against yourselves, and against your peers.  

You also may recall that I feel this program needs to move toward a new competitive metric - one of published ability to deliver savings projected.  This will do for our industry what MPG ratings and JD Power did to the auto industry, it will create incentive to excel around a metric that benefits the consumer and adds credibility to our promises.  It will allow us to market based upon truth and accountability, not smoke, mirrors and hope.  Sell to reason, not fickle emotion.  
A program that can deliver TRUTH is unique in today's marketplace.  This could elevate our profession immeasurably! We may have to go through slight discomfort to get to a better place.  

Tracking before and after energy would be ideal, but right now there is an access problem to energy consumption data "after" improvements.  Until we can solve this, do we have anything that might indicate what results to expect by contractor?  Proxy for energy projection accuracy?  Well, besides "reported energy use before" and "modeled energy use before," we have blower door leakage, projected leakage reduction, and actual leakage reduction.  


CONCEPT INTRODUCTION:  

In my last e-mail I discussed the importance of accuracy of modeling energy input, and provided an image of roughly where you stand against your peers with respect to energy truing accuracy.  The images below/attached show were you stand against your peers with respect to blower door projection accuracy.    Below is PROJECTED reduction, ACTUAL reduction, and Percentage of promise delivered.  In other words, how good are you at projecting?  How good are you at tightening?  And do you sand bag, nail it, or over promise?  (1300 sf house with 10k test in, 9k promise, 3k test out, really?)

There are a lot of ways these early numbers might misrepresent actual work performed.  For example; exaggeration of test in leakage (probably to obtain SIR) could make some look like they are doing more than they are.  (No regression analysis was performed to determine if/which Test In numbers were exaggerated, but I know for a fact people are doing this and suggest that practice stop immediately.)  

The intent of this is to inform not embarrass, so inaccuracy of these numbers helps as they can only help inform, not be used to judge.   But good data matters so going forward there is no amnesty for ANYONE around the data.  





REVIEW:  THESE NUMBERS ARE ALL OVER THE PLACE!!

We all know there is a direct and significant correlation between energy consumption and air leakage.  So it is reasonable to assume leakage reduction has direct and significant correlation to energy SAVINGS.  Accuracy in your blower door projections will show up in your ability to accurately project savings.    

I know these numbers - like the ones I sent last time - may be new to many of you.   What they mean may take a little time to sink in.  But please get your heads around this if you wish to avoid looking incompetent when compared to your peers once this registry goes live!  Again, forewarned is forearmed.  After today, claims of ignorance of harm will not be a compelling defense.  (I keep being asked for names.  The media loves nothing more than to go after contractors taking advantage of "defenseless consumers".)   

Question - What happens when customers you've projected $800 annual savings call you saying they only saw $150?   What happens if your model for them is full of inaccuracies? Over 10 years that's $6500 short.  Let's head that problem off before we get there? 


OBJECTIVE:

We need good inputs to prove Residential Investment Grade Energy Modeling is achievable!  Then we can move to PERFORMANCE BASED INCENTIVES, and ultimately away from the need for any incentives to drive Comprehensive Home Performance.  How nice would it be to show inaccuracy and scatter is caused by poorly designed process and corrupting program incentives rather than by contractors or software?  

It is a forgone conclusion that you will be measured against your peers upon your ability to accurately project savings:  


Inline image 3

(to see these larger go here: http://bit.ly/BDprojpercenthttp://bit.ly/bdactualpercent, and http://bit.ly/bdvariancepercent)


Do YOU Deliver On Promise?  If you want to be at the top of the "delivers on promise" list for energy savings (closest to 100%), make sure your inputs are accurate!  A rising tide raises all boats, except the ones with huge holes.  If you have big holes, plug them now because the tide is coming in.  It appears some people are definitely on the right track, and bravo to you! 



MOVING FORWARD: POSITION YOURSELF FOR TRANSPARENCY AND ACCOUNTABILITY

Apply pressure on CSG and NYSERDA to help you improve air sealing, and prediction.  Make them accountable for helping you succeed.  Position yourself to take advantage of transparency.  

Remember, progress will be a strong defense to poor performance, so let's start tightening things up BEFORE we have tools that expose this work to public scrutiny.  I believe NYSERDA intends to improve reporting.  Demand this so you will not be caught unaware of your numbers in the future.  

Do you really want ME to have your numbers before YOU have them? 


COMPETE FOR RESULTS:  By tracking and competing for results we make Quality measurable.  Great contractors are starting to do this: http://bit.ly/ring4club

I propose a competition for accuracy, which in turn will drive AND REWARD excellence.  It will allow HPwES contractors to TRULY differentiate from Joe Six Pack.

I hope this expresses the importance of blower door input accuracy, and how allowing inaccuracy to go unchecked will be a big problem for YOU when we achieve tracking of savings realization.  


This goal of tracking realization, BTW, may not be far away.  NYSERDA now has direct access to energy consumption whereas before they apparently had to hire 3rd parties to access bills and perform analysis.  

Do I need to spell out what that means?  The registry is right around the corner!   My next e-mail may unearth your ability to deliver savings on promise....

"December Program Update' HERE'S SOME DATA! Letter to Contractors

Below is the letter I sent to contractors about results tracking, and eventually having a way of ranking them based upon their ability to make accurate energy savings projections:

---------- Forwarded message ----------
From: Ted Kidd <tedkidd@eesny.com>
Date: Wed, Dec 12, 2012 at 8:38 PM
Subject: December Contractor Update - Merry Christmas!
To: 


Dear Contractors,

Below are; Some metrics, Competing for results, and a much better way of managing data:

Some of you may be aware that last spring I requested and received a large amount of data under the Freedom of Information Act from NYSERDA regarding your HPwES projects.  

You also may know that I feel this program needs to move toward a new competitive metric - one of published ability to deliver savings projected.  This will do for our industry what MPG ratings did to the auto industry, it will create incentive to excel around a metric that benefits the consumer and adds credibility to our promises.  It will allow us to market based upon truth and accountability, not smoke, mirrors and hope.  Sell to reason, not fickle emotion.  

A program that can deliver TRUTH is unique in today's marketplace.  This could elevate our profession immeasurably! 
Tracking before and after energy would be ideal but right now there is an access problem to energy consumption data "after" improvements.  Until we can solve this, do we have anything that might indicate what results to expect by contractor?  Well, we do have access to "reported energy use before" and "modeled energy use before".  


Certainly someone who uses 1000 therms who has a model showing they use 2000 therms will save 40% is not likely to see 800 therms savings.  


So we can rank ability to accurately model energy consumption pre-improvement with the expectation it will correlate to accuracy of savings projections?  Highly likely.   And seeing these numbers helps contractors understand how accurate their modeling is.   

Do No Harm.  To roll out a ranking or registry without contractor understanding of what is coming is likely to cause harm, so providing this interim step information in a format indicating what will eventually be public information provides opportunity to adjust behavior and policies ahead of time.  Forewarned is forearmed. 

Below is a representation of the data available, and an idea of what a realization ranking might look like.  Those closest to the line have the models that most closely represent consumption of the homes they audit, and those further to the left tend to overstate consumption: (might need Chrome to view)

There is a lot that can be done here, for example these numbers could be run quarterly to show who is improving and who is sliding.  You can't manage what you don't measure, and this should be managed. Nick Taylor is working on making these numbers so people can dig in and understand how to improve results.  You can play with the charts here: http://bit.ly/NickTaylorsCharts

This Christmas I will be receiving a new data set, and a lot of additional information, which I will share with anyone interested.  

I'm also happy to discuss what happens to the work once you commit to tracking results.  (HINT: When you have 2 tests coming up, one you automatically pass just for showing up and the other one is graded, which do you study hardest for?)

Next year NY HPwES will be transitioning from CSG's citrix to Energy Savvy, which looks like a step in the right direction! Maybe NYSERDA will consider tying things to Salesforce and Hubspot.  Things may look discouraging now, but they're poised to get better!  I'd love to hear from those who do not plan to renew their Accreditation, that might be a mistake.  
Sincerely,

P.s.:  Thank you to those who've sent words of encouragement and appreciation.  And as always, to those who wish to be removed from this list please let me know.   

Good faith attempts to remove clearly bad data were made.  The analysis was performed by an independent 3rd party with absolutely no connection or bias toward any NY contractors or the program.  Anyone having issue with accuracy of the data please contact NYSERDA and CSG.

Are You Pro-Active or Re-Active?


Energy Efficiency doesn't mean turning back the thermostat...
...it means Keeping The Heat in the House!



We used to live in really leaky, poorly insulated homes with huge, high output equipment.  The equipment had only one speed, full.   We had a strategy for saving energy - run the equipment as little as possible. 

This was a good strategy.  Heat quickly left the house, so the less you heated the less that left.  Also, over sized single output equipment is able to run more efficiently if it has an opportunity to run for a while. That opportunity occurred when it had to heat the house way up. 


The new strategy is keep the equipment running, matching the building loss, and allowing modern modulating equipment to run at optimum efficiency ALL THE TIME.   


Technology has provided equipment that can modulate output to match the losses or load on the house like you modulate the burner on your stove.   


This new technology requires a new strategy for saving energy.  This new paradigm is the polar opposite of the old strategy, which means it's counter-intuitive, contradicting long held beliefs.  Instead of full off or full on, the equipment gently adjusts up or down to match the need.  


Also, we no longer heat the neighborhood.  We have tighter, better insulated homes.  So lowering temperature doesn't save much, if anything, because it's not cutting losses the way it used to.  In fact, now it may cost energy as the equipment has to go to full throttle for recovery thereby reducing condensing efficiencies. 


Equipment eventually wears out.  Unfortunately most people are not pro-active when it comes to equipment replacement.  Good design and decisions are not accomplished at 2 am on the coldest night of the year when the furnace finally quits for good. 


HOW CAN YOU BE PROACTIVE?  First Step - get your energy history.  

Our houses require a certain amount of heat which usually doesn't vary much from year to year (unless weatherization occurs). There are a number of ways to determine annual gas usage:
  1. Call gas company and ask.
  2. Login to your account and get usage history. (Click HERE for RGE)
  3. Look at current meter read, then look at year ago meter read from a bill and subtract.
  4. Go to the chart in a recent bill and look at each month.  With a straight edge roughly determine the usage and write it down.  Add 12 months usage together.
If you have problems calculating you annual usage feel free to send me your bills and I will try to help.

Next Step:  Get a Comprehensive Home Assessment.

If you'd like to understand your savings opportunity before hand, All you need to know is your heating fuel type, annual amount used, and your homes square footage.  

If you don't know your annual consumption but you do know your annual cost, here's a very basic rule of thumb for determining your energy savings opportunity and if we should schedule a free energy visit.  Based upon past experience:
  • I REALLY WANT TO SEE YOU if you heat with Natural Gas and spend more than $1.00 per square foot per year.  (Oil, Propane, or Electric the number is roughly double)
  • I AM HAPPY TO SEE YOU if you spend $.50 to $1.00
  • I WILL COME TO SEE YOU if you spend less than $.50, but you are either freezing or your house is already fairly efficient.  I hope there are comfort or durability issues you want to address.  Please don't expect miracles when it comes to saving money on energy.
Most people’s single largest energy expense is heating their homes, this also means this is most peoples biggest opportunity for savings.  

And Remember - Equipment that runs gently and continuously is like your car on the highway, running lots of miles with very little fuel.   In the end, every house is different.   You can't know what really saves unless you track behavior and savings.

 If you feel further effort IS warranted, apply for an audit, which may take another 15 minutes.   It's a one page application.  


Ever wonder; "How much am I wasting UNNECESSARILY and WHERE IS IT GOING?"  


STEP 4.  SIGN UP FOR FREE ENERGY AUDIT PROGRAM - it's easy.   It's a one page application.  

If you feel further effort IS warranted, that your house has attractive opportunity for energy savings or comfort improvement, the next small bite is apply for an audit, which may take another 15 minutes:
  1. SIGN UP FOR FREE ENERGY AUDIT PROGRAM - it's easy.   It's a one page application.  Now you have your energy history and know your home has opportunity that meets your cost effectiveness criteria.  Download the PDF and it's "fillable".  

DONE!  Now you have claimed your $250-$400 energy audit.  Actually, reclaimed RPS and SBC charges you've paid in to the system on your utility bill.  


STEP 5.
NEXT BLOG:  FINANCING PROGRAMS THAT USE ENERGY SAVINGS TO PAY FOR IMPROVEMENTS!  On-Bill:  So good it sounds too good to be true!  

Line up the financing.  It's a good idea to get this step started now.  You have nothing to lose and understanding your options here will be really important later.  (Many people find putting this off leads to disappointment and back-tracking.)


The audit opens the door for additional incentives available for funding repairs and improvements through the NY Home Performance with Energy Star program.  Please contact me if you have any questions!

NO MORE CHASING SIR - Dear Contractors, Now We Can Build!!


Group E-mail sent 5/3/2012 - With SIR basically gone, we can re-focus on accuracy, and build a program that delivers on promise:


Dear Contractors,

I'm going to talk about 4 things:  
  1. The recent positive program changes. 
  2. Many haven't fully grasped the changes - some ideas to help with that. 
  3. How this change allows us to get back to focusing on continuously improving the accuracy of our modelling.
  4. Finally, modeled to actual energy consumption ratio is in the area of 1.369324, and this needs to get fixed quickly.  

1. Program Changes - SIR goes away (for the most part)  -  No kidding, no more chasing SIR!!!  

Effective April 1 a change occurred that I think people don't fully grasp.  (Continuous changes to the program had left a lot of people overwhelmed and confused, including me).   Pre-approved Measures no longer require SIR -or- TRC for 10% hemi or 50% aHPwES.  Cost effectiveness of measures is pre-determined, doesn't matter what SIR you get.  

I've heard a lot of complaints about models having no resemblance to the home when they finally get approved, these model contortion efforts can stop.  Now that SIR and TRC are no longer required for pre-approved measures, we can now run everyone through the program for SOME incentive, which is fantastic! 

Even more fantastic - we can run 50/50 (aHPwES) without SIR (something I've never seen before).
And even the loans are not completely off the table for sub 1.01 jobs.  You can "buy down" the loan which means you can borrow up to the project cost TRC and SIR would justify.  Basically they will loan based upon project energy savings.  In other words, if that $10,000 project would make the bar at $6,000, you can borrow that amount and only need to find $4,000 from other sources.    


2.  Getting our heads around this change - Not many attended the webinar, and even if you did the true meaning of recent changes are such a serious easing of restrictions that they may not be very clear.  If it's not clear to you, it's probably not clear to your sales force.  

So how do we convey this to the sales force?

DISCUSS PROGRAM FINANCING.
Some are saying "Just don't do it".  I think if clients are looking for financing, direct them to it but encourage/require completion of your standard financing application also.  Make sure they understand the financing is challenging, and they may not get the whole amount financed through the program.  And remember:  Customers have the option to “buy down” the project cost so that the financed amount meets the cost effectiveness criteria.
DISCUSS ON-BILL.
We lobbied hard for this, and it's a great program.  Again, have your standard financing paperwork.  Explain that clients can buy down the total cost of the job by what the energy savings pays for, so they will only have to get outside financing for the difference. 
This means the additional net monthly cost of improvements to homeowners will only be the monthly cost of the amount not financed through on-bill.  On Bill requires very true TREAT, so this should help provide confidence to clients until we get to Published Realization Rates. 

Now that NYSERDA has removed SIR and TRC hurdles for a significant amount of work, accurate modeling is not an impediment to getting incentives.  Please re-focus on accurate modelling instead of "tweaking to get approval" so when results tracking does occur, you don't put yourself and the program in a difficult spot.  

Please everyone, begin rigorously truing your models, or Realization Rates will continue to deviate from reality.  $1 promised = 63 cents saved does not engender confidence.  When results tracking by contractor becomes public, companies who are not diligent with their modelling run the risk of looking incompetent or worse, fraudulent.  Conversely, those with good realization will have the most powerful sales tool imaginable.

REVIEW THE 3/30 WEBINAR by clicking here: No more chasing SIR!!!


3.  Improve Modelling Accuracy - This requires truing to actual consumption.  

For over a year we've been truing our models.  Not chasing SIR because we see transparency of realization around the corner, and we perceive eventual competitive advantage opportunity here.  That meant very very few 1.01 SIR opportunities.  These program changes means we can finally sell jobs!  

This change means the only reason a contractor might want to game TREAT is to over promise savings to make improvements "payback" better.  I don't think that's something any of us wants to risk.  Leave that for "guy with van, dog, and six pack."  ON BILL has such rigorous modelling requirements I don't think significant gaming can occur.  So pressure on accurate modeling is again going in the right direction!!!


4.  Fix Accuracy of "Promise" - SOME DATA YOU SHOULD ALL BE AWARE OF:

TRUING NOT REQUIRED.  Since the program never required truing, it's something many don't know how to do.  It's extra work.  (PSD has videos showing how to do it.)  Unfortunately, initial models typically grossly overstate consumption.  Overstate consumption and you overstate savings.  So everybody needs to learn to TRUE UP.

From data on completed jobs post GJGNY audit, it appears the models overstate reported consumption by about 36.9324%.  This would lead to the conclusion that even if improvements are accurately modeled, and energy savings % is correct, actual energy & dollar saving will be pretty dramatically overstated.  Truing was optional, that eventually will not be the case.  May as well start truing now for reasons that I hope to make apparent.  

I have calculated consumption overstatement by contractor as well.  If someone else doesn't start ranking contractors using these numbers, I will.  Numbers will be from here forward, not looking back.  SIR cliff made the playing field incredibly unfair, but as of April 1, 2012 that's gone.  From here forward NYSERDA has dramatically fixed the turf, so bad numbers are not justifiable.  

Think of this:  When we can prove $1 promised = $1 saved, selling big jobs becomes child's play.  Winning jobs away from the non- HPwES low bidder will be easy.  Now is the time to correct our modelling so we can point to policy as cause for inaccurate promise during this small window of time, rather than our practices, ethics or cultures.

Again, your audit's modeled and reported energy consumption are publicly available data.  If someone else doesn't start ranking contractors using these numbers, I will.  Eventually I will get Realization Rates as well, the long term goal is to track Realization.  

So accuracy may be a metric you want to think about from a competitive advantage/disadvantage perspective henceforth.  

Cara at CSG added reported consumption to page two of the approval, which makes truing much easier.  She has also added square footage, which allows us to quickly understand the opportunity before the audit.    

Results tracking is coming.  We have time to prepare if we start now.  Please start truing up your models.  Thank you for your time!

If TRANSPARENCY is the answer and FEAR is the barrier, how do we help put fear aside?  ~Ted Kidd, 2012

(Bryan, maybe someone could update the most recent eligible measures list to reflect the changes.  Most recent one on contractor portal is 1/1/12, still states projects must have sir greater than 1.)


****  Note - in looking at the data - there are a fair number of projects that project annual energy savings GREATER than the total annual consumption reported by the customer.   You would think the SIR of these projects would be tend to be predominantly in the 1.01 area, but this appears not to be true.  Possibly due to GeoThermal installs?

How True Are YOUR Models?





Ever wonder how accurate your energy savings projections are?



Like to know what level of confidence you (and your clients) should have in YOUR energy audit software savings projections?



Do you believe in the adage:  Garbage In, Garbage Out?

I have 10+ years worth of energy use, on a spreadsheet.  Doesn't everyone keep such a thing?

You mean everyone is not obsessive compulsive about their fuel use?  Really, you don't have a spreadsheet like this for all their vehicles?  You don't want to know your fuel cost per mile?




OK, I get it.   Clients aren't calling contractors with "Hey, you said I'd save $700 and I only saved $250!!"   People simply are not tracking results.  Nobody cares.

Rather, I think most everyone DOES care (popularity of sites like Fuelly proves people want to roll with this, they just don't want to invent the WHEEL to do it!).  The issue is just not enough to figure out how to do it on their own. 

Gathering energy data is so onerous, bills are so frustrating and confusing, very few care enough to suffer through the effort.  It's as unpleasant as doing taxes with no guaranteed reward, no clear incentive.  Guess it's like hiking.  Sure I like to hike, but I'm not interested in climbing Everest.  Way too much work for a hard to imagine reward at best, non-existent reward at worst.


Well, I wanted to know.  I worried about selling a bunch of hooey, so I kept track.


And for larger projects, the savings is supposed to carry a fair amount of the improvement cost, so failure could be a fair harm to people.  I felt a need for some due diligence.  I even put some time into BLOGGING about projects.


WHAT I LEARNED FROM TRACKING...

Some of what I learned - I learned that if you build an accurate model, true it to actual energy use, put some thought into good, interconnected energy design, and insured the work was done diligently, actual savings exceeded model projections.


SO, WHERE CAN THIS GO WRONG?  

Model Accuracy, Truing Energy Use, Improvement Design, Implementation Diligence, Energy Cost, any place there is a variable that an inaccurate metric is either required ($1.60 therm for natural gas, really!?), or can accidentally be overlooked (If truing is not required, and you are in a hurry to get the work out...), or you need to hit some arbitrary SAVINGS RATIO to have the job qualify for incentives, or it won't sell and you've done 15 hours of work for no compensation... (SIR Cliff).



...If you've made it this far and would like me to continue, please leave a comment or question.
